Application filed. ctober'31, 1917. Serial No. 199,502.

To all whom it may concern:

Be it known that FRANK E. ROBERTSON, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga'and State of Ohio, has invented certain new and a useful Improvements in Suction Cleaning Apparatus, ofl which the following isa specification.- I 1 My invention relates to improvements in dust receptacles for suction cleaning apparatus, and has'for its object the provision of a support and mounting for the fabric dust-container or bag of such devices, which avoids the necessity for any valved detaining member for the contents thereof, and

permits the ready emptying of'the bag,yet holds it securely "in position during use. The receptacle in part, preferably comprises an'integral portion of the fan-casing,

in the portable, electrically-driven: type of apparatus which I have shown in connection with my improvement. Said, fan-casing affords a frameon which thefdus't-bag is removably attached, and a barrier positioned before themouthof the bag or the lower portion thereof, for retaining the contents of the bagtherein. Attaching means,

such as -wedging interiorly placed hoolrs and lugs, or "screw or spring-clamping mechanism, alternatively serve to support thereon, the frameforming the mouth of the bag, removably in place upon the fan-casing.

' Further features of construction and the attendant advantages thereof will. bemore 85 readily understood by making reference to the accompanying descriptionand drawings, wherein w I i Fig. 1 is a view in side elevationof a suction cleaner equipped my improve- 40 i'nents; t

Fig. 2 is an enlarged fragmentary view thereof, partially broken away; I

Fig. 3 is a rear view of the fan-casing with the integral barrier and wedging hooks; g

Fig. 4c is a fragmentary view of an attaching means, and

Fig. 5 illustrates, spring-clip.

Fig. 6 is a fragmentary sectionshowing the dust collected in the upturned bag before the barrier. I

Throughout the several figures of the drawings I have employedthe same character of reference to indicate similar parts.

in section, a co-acting "tension, integral with the casing, is removably mounted the fabric dust-b'agor recepof the bag'is brought accurately and closely The generalfeatures of a well known type of electrically actuated suction cleaner are shown in Fig. 1, of which the suction-nozzle a, the dust-bag b and fan-casing 0 will immediately be recognizedj As shown in Fig.

3 upon a muchlarger scale, the fan-casing comprises. the fan-chamber c with its exhaust-opening 0 and a lateral extension at for the discharge of the fan. Upon this extaclebb The lower portion of saide'xtension is closed by a wall or barrier at, mounting the paired wedging-hooks 03 as best shown at the broken-away portion, Fig. 2.

Co operating withthese hooks OZ are the corresponding lugs e" interiorly positioned within the approximately oval frame 6, reinforcing and shaping the mouth of ba'g b. This frame'e conforms in shape to the rear face of extension d, against'which the frame forming the mouth of the bag is adapted to be brought closely in flush contact, by means of the wedging hooks and co-acting lugs. The oval conformation of the bag mouth best lends itself to thetype 'of fan-casing the seat 0 adjacent to therear of extension d and its seat forthe dust receptacle. When the receptacle is in place, the mouth into register with the ovalportion of the fan-casing. In this position the integral wall 01 forms a complete barrier against the return passage of dust and refuse from said bag, collectingas it must, inthe lower portion of said bag and against the barrier 0?. Thus no valved construction is neces .sary for the retention of the dirt and no external fastening means are required for the bag. t

In Figs. 3 and 4 are shown means, cooperating with the hooks cl. for locking the frame a positively against displacement, if

seat including a free exhaust-opening and a barrier. member, of a dust-receptacle removably posltioned before said extension,

and fitting said exterior seat on the fan casing, and means for removably securing said dust-receptacle to the fan-casing, substantially as set forth.

2. The combination with a suction-cleaner having a motor casing and a fan-casing equ pped with an extens1on affording an elongated exterior seat including a free exhaust-opening and a barrier member positioned beneath said opening, of a dust receptacle having a conforming elongated mouth positioned adjacent to the. motor casing to register with said opening and barrier and extending below the upperedge of the latter, and means for removably'securing the dust-receptacle upon said extension, substantially as set forth.

3. The combination with afan-casing of a portable suction-cleaner, of a fabric dust receptacle, aframe defining the open mouth of said receptacle and adapted to fit upon said fan-casing, wedging means exterior of said casing over which the frame normally is exteriorly positioned to enclose said means,

whereby the open mouth of said receptacle is removably sealed against the' exterior of said fan-casing, and additional locking means interposed between the frame and casing substantially as set forth.

4. The combination with the fan-casing of a suction cleaner, of a dust receptacle, a frame defining the open mouth of ,said receptacle, and rearward wedging hooks and coacting lugs respectively providedupon the fan-casing and the frame,whereby the latter the fan-casin may be removably secured by said lugs in close engagement with the exterior of the fan-casing, substantially as set forth.

5. The combination with the fan-casing of a suction-cleaner, of a dust receptacle, wedging means interposed between the casing and receptacle for removably engaging the mouth of said receptacle with its seat upon and positive locking means upon the casing for retaining said dust receptacle temporarily in place thereon, substantially as set forth.

6. The combination with the fan-casing of a suction cleaner having an exterior seat for its dust-receptacle, an exhaust opening and a dust-retaining member within the boundaries of said seat, wedging hooks positioned upon the casing also within the boundarms of said seat, a frame defining the opening and its dust-receptacle normally supported in inclined position before said dust-retaining member, and interiorly positioned means for engaging said wedging hooks, substantially as set forth.

7. In a portable suction cleaner, the combination with a fa11casing having a substantially vertical exterior seat for the dust receptacle, an exhaust opening and asubjacent dust barrier Within the boundaries of said seat, of upwardly inclined wedging hooks upon the casing, a dust'receptacle nor-- mally supported by said hooks, and means associatedtherewith for engaging the mouth of said receptacle in close wedging engagement with the seat, substantially as set forth.

8. In a portable suction cleaner, the combinationwith a fan casing having a substantially vertical exterior seat, of upwardly inclined wedging hooks laterally provided within its boundaries, a dust receptacle normally supported with its mouth engaging said seat, and means associated therewith for wed'gingly engaging the hooks, substantially as setforth.

In testimony whereof I do now afiix my signature in the presence of two witnesses.
